Mind your P′s and Pt′s! Reaction of a 14‐electron {Pt(dppp)} (dppp=1,3‐bis(diphenylphosphino)propane) fragment, generated in situ at low temperature, or a 16‐electron species [Pt(dppp)(diphenylacetylene)] with 0.5 equivalents of P 4 resulted in the formation of a single complex, incorporating a dinuclear {Pt 2 (μ,η 2:2 ‐P 2 )} fragment (see graphic). A charge decomposition analysis showed four of the five highest occupied orbitals to possess between 39 and 52 % of the electron density on the P 2 fragment.
